A quick and simple way to output some text to a printer is to print to OS logical device attached a printer. For example, on a Windows machine :

 import java.io.*;

public class SimplePrinting {

  public static void main(String[] args) {

    try {
      FileWriter out = new FileWriter("lpt1");
      out.write("Hello world");
      out.write(0x0D); // CR
      out.close();
      }
    catch (IOException e) {
      e.printStackTrace();
      }
    }

}
